PTFE needle felts (also called Telfon ) has excellent resistance to both acids and alkalis, restricted abrasion resistance, and has a maximum operating temperature of 500º F. The PTFE felts are costly due to an intensive production process. In return PTFE has an outstanding thermal and chemical stability.
